referring to fig. 1, 2 and 3: through the installation of the centre gripping handle 6 that the cross-section set up for the arc structure and the setting of the inside sanding pad of more laminating staff of centre gripping handle 6 to and the back of the body setting of bending of lower casing 11 and the whole combination shell body of last casing 1, can realize in the portability welded, through the more comfortable gimmick of taking, reached the promotion to operator endurance, ensured user's when having improved work comfort and held safety.

Referring to fig. 2, 4, 6, 7 and 8: when the laser welding head works, due to the action of high temperature, the condensate on the upper layer of the barrier plate 46 in the condensate storage tank 4 can be rapidly evaporated, gas enters the air plug sliding pipe 42 through the gas guiding action of the gas inlet 48 and the gas flow pipe 47, the backflow phenomenon of the gas is avoided due to the arrangement of the one-way valve ports of the gas inlet 48 and the gas flow port 41, at the moment, the gas entering the air plug sliding pipe 42 starts to push the air plug plate 43 to slide downwards, and due to the arrangement of the reciprocating thread structure at the upper end of the rotating rod 55, in the whole process that the air plug plate 43 slides out of the air plug sliding pipe 42, the rotating rod 55 drives the bevel gear 56 to rotate, and due to the mutual meshing of the side wall of the bevel gear 56 and the right end of the bevel gear rotating shaft 58, the support plate 57 starts to rotate, a process of blowing air inwardly inside is realized, when the gas generated by evaporation presses the gas plug plate 43 to move downwards until the gas plug plate 43 is separated from the gas plug sliding pipe 42, the evaporation gas is discharged through the separation gap between the gas plug plate 43 and the gas plug sliding pipe 42, at the same time, by the inward blowing action of the supporting plate 57, the harmful condensed and evaporated gas is blown toward the end of the activated carbon partition net 54, thereby being absorbed by the active carbon stored at the inner end of the active carbon separation net 54, avoiding the water vapor from accumulating on the inner wall of the condensate storage box 4 for a long time to generate water scale impurities which are difficult to treat under the action of the air pressure of the condensate which is evaporated by heat, meanwhile, the driving action of the bevel gear 56 and the bevel gear rotating shaft 58 is utilized to realize the functions of discharging harmful gases generated by evaporation and auxiliary absorbing of the harmful gases.
